The L3916A offers various features including:
- 2 to 4 wires conversion capability
- Flexibility to adjust the DC path for line current
- Allows parallel phone operation
- Provides limited current supply for external circuitry
- Symmetrical high impedance microphone inputs suitable for dynamic electret or piezoelectric transducer
- Asymmetrical earphone output suitable for dynamic transducer
- Line loss compensation
- Internal muting to disable speech during dialing
- Lighted dial LED consuming 25% of line current
- 32 digits for last number redial buffer
- 18 digits for 13 memory redial
- Allows mixed mode dialing in either tone or pulse mode
- Pacifier tone provides audible indication of valid key pressed in a buzzer and/or in the earphone
- Timed PABX pause
- Flash initiates a timed break of 585ms
- Continuous tone for each digit until key release
- Uses inexpensive 3.579545MHz ceramic resonator
- Powered from telephone line, low operating voltage for long loop applications
Application Scenarios
